IF condition with interval

I want to have a script that runs if the variable X is within 0 and 1. I writed down the following code:

if 0 < X < 1
      statement
else display(NaN)
end

The output script isn't an error but the if condition is not respected and values are away from the interval.

How can I solve this problem. Thanks in advance.

You have to write it as two sub-conditions:

if (0<X) && (X<1)

Thanks a lot for help!

if (0<X && X<1)

...also works with multiple conditions.
